stratovolcanoes
Central Chile and Argentina (South America), -40.77°S / -72.15°W 
Summit height: 1990 m / 6,529 ft
Current status: normal or dormant (1 out of 5)
Last update: 22 Dec 2021 (increased seismic activity)
The Antillanca group of stratovolcanoes is located 100 km NE of Puerto Montt in central Chile, at the eastern shore of Rupanco Lake. The cluster consists of scoria cones, maars and small stratovolcanoes and covers an area of 380 sq km.
The most prominent volcanic edifice is the Casablanca stratovolcano which erupted about 2910 and 2260 years ago.
Older stratovolcanoes of the Antillanca group include Sarnoso volcano on the SW side and Fiuchá volcano on the NW side.
Geothermal areas are found in various spots on the NW side of the group.

Remark:
Our list of volcanic eruptions closely follows the database of eruptions of the Smithsonian's Global Volcanism Project (GVP), the internationally most recognized data source for volcanic eruptions, but also includes significant eruptive episodes or related volcano events. "Volcanic eruptions" are usually to be understood as sequences of individual eruptive episodes that can follow each other, or even overlap (if several vents are involved), and can last many years, decades or even longer. For example, the current activity of Stromboli volcano is understood as a single eruption that has been ongoing since 1934.
